Dimethylethanolamine boils at 134.1 °C (273.3 °F; 407.2 K). This means that if the pressure is 1 atmosphere, it will evaporate at 134.1 °C. The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the external pressure surrounding the liquid.

Dimethylethanolamine is a colorless, viscous liquid with an amine-like odor. It is used in a variety of industrial applications including the production of resins, pharmaceuticals and cosmetics. It is also used as a corrosion inhibitor and defoamer.
